I whipped these up after lunch today from some plump blackberries I bought this week. They came out real good. You could also make this up as a loaf.
Blackberries are sure plentiful in my local stores lately and they're coming down in price some, too. These are a pleasant change from the strawberry, raspberry or blueberry muffins I usually make. These could also be made with some drained crushed pineapple or mashed banana, if you’re to the “other fruits” rung yet. The recipe, as written, is not acceptable until the nuts and berries rung of the OWL ladder. If made up as a loaf in a greased loaf pan, this will take about 40 minutes to cook.

DIRECTIONS: Preheat oven to 350º. Melt butter in large bowl. Beat in the 5 eggs. Add cream and liquid Splenda. Stir well. Measure and add in all the dry ingredients and stir to blend. Fold berries gently into batter but do not over work them or they will turn your batter dark. Line with paper or grease 12 muffin cups. Using ¼ c. measuring cup as a scooper, scoop ¼ c. batter into each cup. Use up any remaining batter evenly in the 12 muffins. Sprinkle the tops with the tablespoon of granular erythritol if using. Pop into preheated 350º oven and bake for 20 minutes or until firm to the touch in the centers. These should freeze well.

I know nothing about Swerve. But no, this is not the equivalent of a cup of sugar. 20 drops of EZSweetsliquid sucralose on my bottle says it's equivalents to 20 tsp. of sugar or 6T.+2tsp. Each packet of my Spring Valley stevia extract (with filler) is equal to a tsp. of sugar. And the 1T. of erythritol is slightly less sweet than 1T. sugar. So my recipe has more like about 9T. sugar or a little over 1/2 cup. I'd start with that amount of Swerve equivalent and bake one batch to see if that's to your liking.

I find you really just have to experiment with sweeteners in recipes, as every one is different and everyone's taste is different. It's all about trial and error to get it as sweet as YOU like. I've found every dessert I bake isn't sweet enough for me on first baking. It usually takes a second and sometimes a third trial before I get a recipe just as sweet as I like without getting it TOO sweet.

Peggy, thanks for steering me away from the one cup equivalent. I know it takes trial and error, but I've had way too many errors and since some of these sweeteners are so expensive, I hate to get it so wrong it's inedible. Which I've done!

Sure thing! Man, I've had my share of sweetener errors, too, JLx. I suspect we've all worn those shoes a time or two. And I still, after 3 years of using them, have the occasional sweetener disaster, where a muffin/cake tastes like I didn't put any sweetener in it at all!! So feel free to learn right along with the rest of us, my dear.
